Rear light cover/lense re attaching

[Milky400]

hi,

Rear light cover rather loose at the moment and about to drop off. suggestions on re sealing it please.

Is it a case of removing it and re doing, if so how easy is this? (not briliant with a mastic gun) and how do you remove the old stuff from the lense and body.

Cheers

Don't think Mastic does it, I think you need Silkaflex. Pretty easy job, just gently remove the lens and rub/pull/trim the old stuff off, run a bead around the lens, or body, press to fit, tape up til it's set.

Silkaflex does the job right

sikaflex will do the job. Do not use black silicon, it doesnt work. I speak from experience of having to do both sides again after using silicon the first time.

If its still attached run a craft knife around the edge through the sikaflex (its like black rubber) to release the lens. Rub off / cut off what you can then reseat on a bead of sikaflex. Then run a bead all around the edge of the lens and (in my case) run a finger around to smooth it down (having masked up first). Once finished you can remove any excess sikaflex from the paintwork before it dries using a dab of white spirit.

Make 100% sure your bedding in bead and then the edging is continuous with no gaps or you will get condensation inside.

Its horrible stuff and gets everywhere, I masked all the way around the outside of the lens before refitting, saved lots of aggro later.

Sikoflex is just the ticket, Mine have stayed put for about three years now and show no signs of falling off.
Be warned though by the time you have the top off it'll be all over every door handle in the house the wife will have black hand prints were she shouldn't and the inlaws will turn up to spread it about a bit.

Worth wearing throw away gloves for.

Don't forget the internal black paint line to hide the mastic work. Previous owner had done a good job with mastic but no paint line - so I had to remove and redo - couldn't get Sikaflex over Xmas so used Tiger seal.

The lenses have a black internal line around the edge which covers the mastic and gives a clean 'line' to the unit.
